Indoor wall verticality and flatness laser tester

The utility model relates to a laser tester for perpendicularity and flatness of an indoor wall. An existing interior wall perpendicularity and flatness inspection device is not visual and needs calculation. Therefore, the device comprises a linear laser generator and an adjustable tripod, the adjustable tripod comprises a horizontal base plate, a three-cutting seat, three hinged short rods and three supporting legs, and the upper surface of the horizontal base plate is provided with a longitudinal liquid bubble level meter and a transverse liquid bubble level meter respectively. Two vertical shafts perpendicular to the upper surface of the horizontal substrate are respectively arranged on the upper surface of the horizontal substrate, the two linear laser generators are respectively sleeved on the two vertical shafts and can rotate around the respective vertical shafts, and a laser surface emitted by each linear laser generator coincides with the axial lead of the vertical shaft where the linear laser genera
